Question

Describe the relationship of the atoms shown by:

Answer 1

Answer is A) The rearrangement of atoms is a chemical change.

Ch4 +2O2 ⇒ CO2 +2H2O

(Methane + Oxygen → Carbon dioxide + Water)

Methane gas reacts with Oxygen, and it causes combustion, producing carbon dioxide and water vapor to Atmosphere.  

Answer 2

Answer:

A) The rearrangement of atoms is a chemical change.

Explanation:

A chemical change is a process in which new substance (product) is formed due to a chemical reaction. Chemical reaction give rise to a chemical change can occur by simply applying heat to a substance.

In the chemical reaction symbolized, a molecule of methane reacts with two molecules of oxygen to produce carbon (IV) oxide and two molecules of water.

i.e                  $CH_{4}$ +2$O_{2}$  ⇒  $CO_{2}$ + 2$H_{2}O$

Thus, the relationship of the atoms shown is the rearrangement of the atoms of reactants to give new products due to a chemical reaction.
